               1.      Calculate the Pearson r correlation.

               2.      Interpret the form, direction, and strength of the
                       correlation.

               3.      Provide the research conclusion based on the correlation
                       value.

               Please circle the best possible answer from given options.

               1.      Which of the following correlations shows the weakest
                       relationship?
                       a.     0.98
                       b.     0.01
                       c.     -0.22
                       d.     -0.90

               2.      When a perfect linear relationship exists between variables
                       X and Y, what does r equal?
                       a.     -1 only
                       b.     0
                       c.     +1 only
                       d.     Either -1 or +1

               3.      Which of the following sets of correlations correctly shows
                       the highest to the lowest degree of relationship?
               1.      +.83, -.91, +.10, -.03
               2.      -.91, +.83, +.10, -.03
               3.      +.83, +.10, -.91, .-03
               4.      +.83, +.10, -.03, -.91
